岩棉板又称岩棉保温装饰板，是以玄武岩为主要原材料，经高温熔融加工而成的无机纤维板，是一种新型的保温、隔燃、吸声材料。目前做隔音用玻璃棉比较多。那么济南岩棉板与玻璃纤维棉的区别是怎样的呢？

Rock wool board, also known as rock wool insulation decorative board, is an inorganic fiber board made from basalt as the main raw material and processed by high-temperature melting. It is a new type of insulation, flame insulation, and sound absorption material. Currently, there are many glass wool materials used for sound insulation. So what is the difference between Jinan rock wool board and glass fiber cotton?

1.岩棉是矿渣为原料，玻璃纤维棉是精矿为原料（石英石矿）；

1. Rock wool is made from slag, while glass fiber wool is made from concentrate (quartz ore);

2.岩棉的纤维丝较粗较短（岩棉需要更高的密度、更厚些才能成形），玻璃纤维棉纤维丝更细更长，所以相同密度的情况下玻璃纤维棉会更结实，结构会更错综复杂，因此玻璃纤维棉的吸音系数会更高；

2. The fiber fibers of rock wool are thicker and shorter (rock wool requires higher density and thicker to form), while the fiber fibers of glass fiber cotton are thinner and longer. Therefore, under the same density, glass fiber cotton will be stronger and its structure will be more complex, resulting in a higher sound absorption coefficient of glass fiber cotton;

3.岩棉的纤维丝比较粗比较短，在成板是没那么结实，容易出现松散的现象，特别是在密度低于100KG的情况下，如果填充在隔墙内，容易出现松垮的现象，时间久了棉就会往下垮成一跎，失去刚开始安装好时的隔音效果，而玻璃纤维棉密度超过32KG时就不会出现这种情况；

3. The fiber fibers of rock wool are relatively thick and short, which are not as strong as the finished board and are prone to loosening, especially when the density is less than 100KG. If filled in the partition wall, it is easy to collapse. Over time, the cotton will collapse and lose its sound insulation effect when it was first installed. However, this situation does not occur when the density of glass fiber cotton exceeds 32KG;

4.相同密度、厚度的情况下，刚安装好时，玻璃纤维棉的吸音、隔音效果，大概是岩棉的1.2倍左右；

At the same density and thickness, when first installed, the sound absorption and soundproofing effect of glass fiber cotton is about 1.2 times that of rock wool;

5.二种材料同为A级防火材料，都是纤维丝制品，碰到人身上会痒，都不环保的，岩棉相对会更痒；

5. Both materials are A-grade fireproof materials, both of which are fiber silk products. They will itch when they come into contact with people and are not environmentally friendly. Rock wool will relatively itch more;

6.岩棉耐高温大概500度，玻璃纤维棉耐高温大概200度，二种材料的导热系数相当，岩棉现多应用于保温隔热方面，玻璃纤维棉现多应用于吸音隔音方面。

6. Rock wool has a high temperature resistance of about 500 degrees Celsius, and glass fiber cotton has a high temperature resistance of about 200 degrees Celsius. The thermal conductivity of the two materials is equivalent. Rock wool is now mostly used for insulation and insulation, while glass fiber cotton is now mostly used for sound absorption and sound insulation.

岩棉板除了保温隔热还能隔音降噪。岩棉的吸音效果不能光看厚度，还要看岩棉的容重还有表面是否有吸引冲孔，做隔音墙必须采用几种不同性质的材料，比如在承重的砖墙前加隔音材料，按防火要求，采用100毫米厚的岩棉，封闭后再用柔性面料装饰即可达到要求。你有需求可以随时来我们网站http://www.jnhxtcg.com咨询！

Rock wool board not only provides insulation and insulation, but also provides sound insulation and noise reduction. The sound absorption effect of rock wool cannot be solely determined by its thickness, but also by its bulk density and whether there are attractive punching holes on the surface. Several different materials must be used for soundproofing walls, such as adding soundproofing materials in front of load-bearing brick walls, using 100mm thick rock wool according to fire protection requirements, and decorating with flexible fabrics after sealing can meet the requirements.
